%/L ATTORNEYS mask in position, but, in any event, the said mask will be positioned at a height to space the same from the top and sides'of the upper Water tank 13 of the radiator to provide an ample air passage therebetween. The relative size and form of the mask 16 and its grid 17,'are such that the opening occupied by said grid Will extend at the top, as indicated at 21, to the height of the tank 13, thereby providing not only a direct opening through the grid 1'7 to the radiating section 16, but also, through the said grid 17 directly to the front of the said tank.

By the described arrangement air will be directed fully against the front of the tank and a current of air under pressure Will be caused to pass over and at the sides ofthe tank in contact therewith and between the same and "the innerside of the mask 16 and thence through hood 18. This is so be cause, as will be. obvious, the air striking the front of the main radiator tank can have no outlet except rearwardly through the air passage between the radiator and the shell 16 since the forward extension on said shell beyond the radiating section and radiator tank affords no other avenue of air escape. Moreover, the plenum produced by the air striking the tank and by reason of the fact that the total frontal area presented by the cellular section to the air is greater than the area and capacity of the air cells, so that the resulting plenum produces an effective cooling current through the air passage beneath the spaced shell. I thus materially increase the efficiency of the radiator and particularly is this true when my invention is employed on cars having that type of radiators provided with a casing of enameled sheet iron or steel, which latter form, it being known, leaves much to be desired in efiiciency as compared with radiators without these enameled casings. The shell also provides spaces for the passage of air between the sides of the radiator and the sides of the shell.

The mask 16, it will thus be seen, provides a shell between which and the radiator tank, a current of air is induced. In order to augment the cooling action of the air striking against the front of the radiator tank and passing over and at the sides thereof as described, I form upon or secure to the said tank radiating fins in the form of plates. At the front of the tank 13 plates 22 extend therefrom forwardly within the grid 17 The plates 22 may have transverse holes 23 suitably disposed therein to increase the air contact. At the top and sides of the tank 13 in the rear of the plates 22 and preferably in line therewith, are radiating plates 24, which, preferably, are approximately perpendicular to the surface of the tank at the top and sides. These plates, 22, 24, preferably extend to a contact with the under necessaaccommodating the hood 18 flush. with the said structure 16.

The hood 18 is formed in panels and 1 provide at the upper hinge joint 25, the inside thereof, gutters to conduct forwardly any drip passing. through the hinge oint, thereby protecting the motor from said drip. The joint 25 may be formed by bending knuckles on the respective panels about a' hinge pin or rod 26. The gutter is preferably curved transversely as at 27 and a lateral extension or flange thereof is riveted as at 28, or otherwise secured to one panel, the curved gutter extending beneath the hinge joint to the opposite side as clearly seen in Fig. at.

The side hinge joints 25 of the hood are preferably formed as shown in Fig. 5, in which it will be seen that one panel of the hood extends downwardly beyond the adjacent hinge joint as at 29.and overlaps at the' outside the offset or depressed upper edge 30 of the adjacent side panel of the hood. The hinge joint 25 at each side of the hood will thus be located above the lower edge 29 of the upper panel and at the inside of the same. The joint may be formed by bending knuckles on the, respective panels about a hinge rod or pin 26*.

The shell, with its grid 1? and the hood 18," being independent of the particular structure and form of the radiator, may be made to effectively mask the radiator and be given lines to produce stream line effects. Thus, the esthetic value of the mask covered by my patent above referred to is preserved 'While the utility of the attachment is greatly increased.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:

1. In a radiator, a Water tank, and means to mask and cool said tank, said means comprising a covering shell open at the front' and back, and spaced from the said tank to form an air pamage over the top of the tank and at the sides thereof between said tank and the said shell, said passage being in free comnmnication with the open front of the shell, the said shell extending forwardlv beyond the tank, a grid in said shell at the front, and spaced radiating elements on said these radiating plates tank at the front within said grid and at the top and sides of the tank in the said air passage, said shell and the said grid affording an entrance of air direct to and against the frontof the tank.

2. In a radiator, a water tank, and means to mask and cool said tank, said means comprising a covering shell open at the front and back, and spaced from the said tank to form an air passage over the top of the tank and atthe sides thereof between said tank and the said shell, said passage being in free rommunication with the open front of the shell, the said shell extending forwardly beyond the tank, and spaced radiating elements on said tank at the front at the top and sides of the tank in the said air passage formed by the tank and shell, said shell affording an entrance of air direct to and against the front of the tank.

8, in an apparatus of the class described including a water tank and a shell supported over the tank and spaced therefrom to form an air passage over-the top of the tank and at the sides thereof, the said shell being open front and back in free communication with the said air passage and adapted to direct a current of air through the said passage; together with radiating elements on the tank and extending from the same forwardly toward the front opening of the shell, and extending upwardly approximately to the inner surface of the shell.

4. An apparatus of the class described including a radiator having a'water tank at the top, a covering shell over said radiator and tank and spaced therefrom at the top and sides to form an air passage between the said shell and the said radiator and top tank, the shell being open front and rear in free communication with the said air passage to cause a current of air to pass therethrough, and a motor hood at the rear of the shell in line with the latter, said hood having support at its front end on the shell so that the one is complementary to the other, and the interior of the hood being in free communication with the said radiator and the said air passage.
